Congrats! I love those Seth Lover designed Fender Humbuckers. True, the classic Tele sounds are a bit out of reach, but both the Deluxes and the Customs (neck humbucker only) are GREAT all around guitars! I've had two Customs (one with a Bigsby I couldn't do anything with, though it appreciated in value exponentially while I owned it a few short years).
I have sought out those Fender Humbuckers for project guitars, though they've gotten scarce now. I like them better than any other humbucker on the planet! They're sweet. Just right for kick butt bridge or nice jazz neck. Easy to work on too, for coil splitting, etc.
I happen to like micro-adjust necks too, fashion be damned.
Sounds like you scored a winner guitar!
